8 OMII_2 Release  50 downloads of OMII versions from website so far (pre Release 6)  OGSA-DAI WSI-1.0 will get a customised OMII bundle –there have been some issues as OMII1_2 and OGSA-DAI R6 use different versions of Axis –this should be resolved in the OMII2_0 release –the same feature set as the GT4 version  Still want to use GRIMOIRES registry –To explore its use for data resource & services –Registering service functionality –Registering data content –To avoid doing our own from scratch  Expecting to use WS-Addressing for R7 on OMII_2_x

9 GT4 WS-RF Release  Moving from contributed component to core component in Globus Toolkit 4.0 –Released service only release with GT4.0 –Releasing full OGSA-DAI WSRF-1.0 package with GT4.0.1  Almost all features from OGSA-DAI OGSI r6.0 for GT4.0.1 –registry not being actively developed (awaiting alternatives) –no factory, making concurrency more difficult (to be fixed in R7) –security: switch from MLS to TLS in GT4

10 Applications and Collaborations  caBIG –collaboration continues –have also made contact with Peter Maccallum of UK CancerGrid project  NGS –working with Matt Ford to understand how to promote Data Services on the NGS –ConvertGrid the first project using OGSA-DAI on NGS  Exploring other opportunities –EDINA, map services –Reading eScience Centre, Met Office data –Sybase, support for new databases

11 Training and Dissemination  Tutorials: –GlobusWorld, Boston –GGF13, Seoul –UK Globus Week, NeSC –Forthcoming International Grid Summer School, Vico Equense  Many presentations including: –PRISM –Introduction to the NGS –PPARC eScience Postgraduate School  Papers: –“The design and implementation of Grid database services in OGSA-DAI “, Concurrency and Computation: Practice and Experience, Volume 17, Issue 2- 4, Pages 357 – 376, Feb –"Introduction to OGSA-DAI Services" Lecture Notes in Computer Science, LNCS Vol. 3458, pp. 1-12, Springer, –Two papers accepted from team at AHM Architecture and Status + Benchmarking

12 More dissemination  UG Meeting –June 1 st at NeSC –Panel of five projects –Participants from three continents  UK Projects Meeting –July 18th at IBM South Bank –Give an introduction to OGSA-DAI, OMII and NGS  First DIALOGUE workshop –August 1st – 2nd at Columbus, Ohio –follow on meetings between projects –bringing together data integration projects –Second workshop November at NeSC  AHM Workshop on Data Integration –7 papers accepted

13 Release 7  Features: –Recommended registry with Client Toolkit support –Security (WS-RF, Authorisation interface) –Sessions and Transactions support –Seamless Multiplatform Client Toolkit –Integration of DQP –Data Service Concurrency –New OGSA-DAI Engine design –Provide DAIS Spec implementations  Additionally, potential to prototype some of: –DFDL –Extended support for Data Integration –Extended support for Files (e.g. Datacutter) –XQuery –OO Data Resources  Expected release in September 2005

14 Research Team  NESC: –Detailed design, prototyping and evaluation of updated OGSA- DAI architecture, including functionality enhancements. Concurrency, sessions, Tx, monitoring, naming and data transport –User support/outreach/training. –Schema integration & XML technologies from Q4 05 onwards –Performance evaluation

15 Architecture v2  A fresh look at the architecture of OGSA-DAI –Performance analysis –Provision of additional features –Integration of security –Provision of better integrated tooling and developer support –Better integration with other data services –Extensions to provide monitoring dynamic management dynamic configuration  Ongoing meetings to discuss –Architecture Paper accepted for All Hands Meeting –Leaving architecture in good stead for future work –Stabilising developer interfaces (especially Activity API) BEFORE R7
